Which of the following is an example of a technology-based physical security measure?

Surveillance cameras are a prime example of a technology-based physical security measure because they utilize electronic equipment to monitor and record activities within a designated area. This technology serves multiple purposes, including the deterrence of criminal activity, real-time monitoring, and the ability to gather evidence if an incident occurs. The integration of advanced features like motion detection, night vision, and remote access further enhances their effectiveness in protecting premises.

In contrast, options such as security staff are reliant on human presence and observation rather than technology, whereas barbed wire fences and natural landscapes represent physical barriers that do not involve technological components. Therefore, surveillance cameras exemplify how technology can be employed to enhance security in various environments.
